The process cartridge is a cartridge that can be detachably incorporated into a main body of an image forming apparatus, and includes, as an integral unit, an electrophotographic photosensitive member and at least one of processors such as a charger, a developer, a cleaner, and the like. Since the process cartridge is detachably mounted with respect to the apparatus main body, maintenance of the apparatus is facilitated. An electrophotographic image forming apparatus employing an electrophotographic image forming process is operated such that an electrophotographic photosensitive member uniformly charged to a charger is selectively exposed by light of the image forming apparatus to form an electrostatic latent image, the latent image is developed with toner for a developer into a toner image, and the formed toner image is transferred onto a recording medium by a transfer machine to form an image on a recording material.
In the prior art, a plurality of manufacturers adopt a telescopic power receiving device, a control mechanism for controlling the telescopic power receiving device is arranged on one side of the processing box to realize the engagement of the power receiving device and a driving head in the imaging equipment when the processing box works, and the power receiving device is disengaged from the driving head when the processing box is disassembled, for example, a control mechanism is disclosed in Chinese patent publication No. CN102385300A, and comprises a control rod capable of rotating around a supporting point on the box body and a spring for controlling the control rod to rotate, and the control mechanism can control the power receiving part on the processing box to stretch to realize the engagement and the disengagement with a machine driving device. With this structure, when the size of the process cartridge is further limited such that the retraction stroke of the above-described power receiving portion is limited, the power receiving portion cannot be completely disengaged from the drive head in the image forming apparatus, resulting in difficulty in taking out the process cartridge.
In addition, chinese patent publication No. CN105843008a discloses a driving force receiving assembly of a photosensitive drum, in which an installation angle of a power receiving portion when the power receiving portion is installed into an image forming apparatus is adjusted by using a combination of a position adjusting device and a rotating device, the power receiving portion is deflected to both sides to disengage from a driving head in the image forming apparatus, and since the power receiving portion cannot be deflected by 360 degrees, the power receiving portion cannot be deflected normally at certain angles to disengage from engagement, and at the same time, the power receiving portion may be deflected during power transmission to cause unstable power transmission.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Example 1
As shown in fig. 1, the process cartridge of the present invention includes a housing 1 having a developer accommodating portion, a handle 7 provided at a rear end of the housing, a rotating member (not shown) provided at a front end of the housing 1, which may be a member such as a photosensitive drum or a developing roller, a driving assembly 10 provided at a side end of the housing 1, and the driving assembly 10 receiving a driving force in an image forming apparatus and driving the rotating member to rotate. The processing box is also provided with a force bearing part 2 which is arranged on the same side with the driving component 10.
As shown in fig. 2, the process cartridge of the present invention is shown in an exploded structure on the side of the force receiving portion 2, wherein a mounting portion 5 is provided on the housing 1, one end of the first elastic member 3 abuts against the mounting portion 5, the other end abuts against the force receiving portion 2, and the cover 4 covers the force receiving portion 2 and the first elastic member 3 to prevent the force receiving portion 2 and the first elastic member 3 from coming out. The drive assembly 10 includes a power receiving portion 11 having a pair of claw portions 11a protruding in the direction of the rotation axis of the power receiving portion.
As shown in fig. 2 to 4, the driving head 50 in the image forming apparatus includes a pair of power output arms 50a. When the process cartridge is mounted in the image forming apparatus in the direction of arrow D in the drawing, the power receiving portion 11 may have two states with respect to the driving head 50, the first state being as shown in fig. 3, fig. 3 being a state in which the penetrating direction X of the opening formed between the pair of claw portions 11a faces the driving head and the power output arm 50a of the driving head 50 stays at a position not interfering with the claw portions 11a, at which time the power receiving portion 11 may pass directly through the driving head 50 and stay at a position coaxial with the driving head 50, and after closing the machine door cover of the image forming apparatus, the image forming apparatus drives the driving head 50 to rotate and engages with the power receiving portion 11 to drive the power receiving portion to rotate, that is, this first state is a state in which the power receiving portion 11 does not interfere with the driving head 50 in the image forming apparatus during the mounting of the process cartridge. The second state is shown in fig. 4, in which the claw portion 11a of the power receiving portion 11 interferes with the driving head 50, at this time, the machine door of the image forming apparatus is closed, the machine door presses the force receiving portion 2 to keep the power receiving portion 11 in contact with the driving head 50, when the image forming apparatus drives the driving head 50 to rotate, the power output arm 50a of the driving head 50 contacts the claw portion 11a of the power receiving portion 11 and rotates the power receiving portion 11 by a certain angle, and when the power receiving portion 11 rotates to the position of fig. 3 while the driving head 50 also rotates to the position of fig. 3, the power receiving portion 11 passes through the driving head 50 and stays in a coaxial position with the driving head 50 and then completes engagement with the driving head 50 to receive the driving force. Alternatively, the force receiving portion 2 may receive a force at a position other than the machine door in the image forming apparatus to maintain the contact of the power receiving portion 11 with the driving head 50. In addition, the force receiving portion 2 may be fixedly provided on the housing 1, and may receive the force of an elastic mechanism in the image forming apparatus to maintain the contact of the power receiving portion 11 with the driving head 50. In a part of the image forming apparatus, the mounting direction of the process cartridge into the image forming apparatus is inclined downward in the gravity direction, and in this state, the process cartridge may not be provided on the force receiving portion 2, and the contact of the power receiving portion 11 with the driving head 50 can be achieved by utilizing the gravity of the process cartridge.
As shown in fig. 5 and 6, the image forming apparatus has a left side plate 101 and a right side plate 102, the process cartridge is supported between the left side plate 101 and the right side plate 102, and the casing 1 of the process cartridge is inclinably movable between the left side plate 101 and the right side plate 102. When it is necessary to take out the process cartridge, the machine door in the image forming apparatus is opened, the handle 7 is grasped, and the process cartridge is pulled outward, and since the power receiving portion 11 and the driving head 50 are in the engaged state at this time, the process cartridge is smoothly taken out in a posture of rotating and tilting about the engagement point of the power receiving portion 11 and the driving head 50 as a fulcrum.
Example 2
Next, embodiment 2 of the process cartridge of the present invention will be described, embodiment 2 of the present invention differing from embodiment 1 only in that an adjusting mechanism is added to adjust the fitting position of the power receiving portion 11 and the driving head 50, as shown in fig. 7, the driving assembly 10 in embodiment 2 of the present invention is provided with an adjusted portion 11b having an elliptical cross section on the power receiving portion 11, and a flange 15 for receiving the driving force of the power receiving portion 11 and transmitting to the rotatable member in the process cartridge. An adjusting member positioning member 13 is further provided adjacent to the power receiving portion 11, the adjusting member positioning member 13 being engageable with the housing of the process cartridge to prevent rotation of the follower power receiving portion 11 thereof, the adjusting member 14 being mounted in the adjusting member positioning member 13, the adjusting member 14 being provided in this embodiment as a torsion spring having one end abutting against the regulated portion 11b on the power receiving portion 11 and the other end abutting against the regulated portion 13 b on the power receiving portion 11, while the power receiving portion 11 being provided with a certain free clearance in the rotational direction with respect to the flange 15, the adjusting member 14 being engageable with the regulated portion 11b to adjust the position of the power receiving portion 11 to the state shown in fig. 3, that is, to ensure that the penetrating direction of the opening portion formed between the pair of claw portions 11a is mounted in a posture facing the driving head 50 every time the process cartridge is mounted in the image forming apparatus in the mounting direction D. This arrangement can reduce the probability of the process cartridge being mounted into the image forming apparatus where the power receiving portion 11 interferes with the driving head 50, and at the same time, can reduce the angle at which the power receiving portion 11 needs to be rotated by the driving head 50, which can make the mounting of the process cartridge smoother and can increase the service life of the driving head.
Example 3
Next, embodiment 3 of the process cartridge of the present invention will be described, and embodiment 3 of the process cartridge of the present invention is different from embodiment 2 in that when the power receiving portion of the process cartridge is in contact with the driving head in the image forming apparatus, the power receiving portion of the process cartridge also has a certain amount of play so that the power output arm of the driving head can cut into between a pair of claw portions of the power receiving portion when the driving head rotates.
Specifically, as shown in fig. 8 to 10, the claw portion 11a has a facing portion 11a2 facing the rotation axis of the power receiving portion 11 and a side surface 11a1 adjacent to the facing portion. The drive head 50 further includes a front end cylindrical portion 50b provided at the lower end of the power output arm 50 a. The pre-engagement state of the power receiving portion 11 and the drive head 50 in this embodiment is the same as that in embodiment 2, in which a part of the front end cylindrical portion 50b of the drive head 50b is first cut into the gap formed between the pair of claw portions 11a, and then the power output arm 50a is brought into contact with the side face 11a1 of the claw portion 11 a. In this embodiment, when the printer drives the drive head 50 to rotate after closing the machine door cover of the printer, since the power receiving portion 11 is provided with a certain amount of play, the power output arm 50a of the drive head 50 will force the claw portion 11a of the power receiving portion to move in the arrow R direction in the drawing, which is the direction in which the claw portion 11a moves away from the axis in the direction perpendicular to the axis of the power receiving portion, and then the power output arm 50a cuts into the formed gap between the pair of claw portions 11a and comes into contact with the facing portion 11a2, and as the drive head 50 rotates further, the power output arm 50a slides over the facing portion 11a2, the claw portion 11a moves in the S direction opposite to the R direction in the drawing, and finally the power receiving portion 11 and the drive head 50 are in the normally engaged state as shown in fig. 10, which means the power receiving portion 11 is in the substantially coaxial state with the drive head 50.
Example 4
Next, embodiment 4 of the process cartridge of the present invention is described. As shown in fig. 11 to 13, the present embodiment is different from the first embodiment in that when the power receiving portion 11 is in a pre-engagement state with the drive head 50 and is in contact, after the drive head 50 rotates, the power receiving portion 11 is not driven to rotate by the drive head 50 any more, but the drive head 50 is caused to move in the axial direction so that the power receiving portion 11 is engaged with the drive head 50. Specifically, in the present embodiment, as shown in fig. 11, the driving head 50 of the image forming apparatus is provided to be elastically movable, and a second elastic member 51 is provided between the driving head 50 and the inner wall of the image forming apparatus, which allows the driving head 50 to be telescopically movable in the direction of its own rotation axis. When the door of the printer is closed, the drive head 50 starts to rotate, and by the abutment of one side surface 11a1 of the claw portion 11a of the power receiving portion 11 with the power output arm 50a of the drive head 50, the drive head 50 is caused to move in the direction of arrow M in the drawing against the elastic force of the second elastic member 51, which is the direction of the rotational axis of the drive head 50 and which is the direction away from the claw portion 11 a. With the retraction of the drive head 50, the power output arm 50a will retract most to a position out of contact with the side face 11a1 (see fig. 11) of the claw portion 11a, which is a position where the power output arm 50a is out of contact with the side face 11a1 of the claw portion 11a and is no longer blocked by the side face 11a1 in the axial direction of the power receiving portion 11, where the power output arm 50a of the drive head 50 will pass over the claw portion 11a from the tip end of the claw portion 11a, and after the power output arm 50a passes over the claw portion 11a, the elastic force of the second elastic member 51 pushes the drive head 50 out in the direction approaching the claw portion 11a in the axial direction, and finally, the power receiving portion 11a and the drive head 50 enter a normal engagement state as shown in fig. 13, which is a position where the power receiving portion 11 is substantially coaxial with the drive head 50.
Example 5
Next, embodiment 5 describing the process cartridge of the present invention is described. The present embodiment is different from embodiments 1 to 4 in that the partial shape of the driving claw 11a of the driving force receiving member 11 is changed. As shown in fig. 14, the facing portion 11a21 of the claw portion 11 of the power receiving portion 11 facing the axis of the power receiving portion 11 in the present embodiment is provided in an outwardly expanding tapered shape, in other words, the distance between the facing portion 11a21 and the axis of the power receiving portion 11 increases as the distance of the facing portion 11a21 from the flange 15 in the axial direction increases, measured along an axial square perpendicular to the power receiving portion 11. By this arrangement, the power output arm 50a of the driving head 50 can be made to cut into the gap formed between the pair of claw portions 11a more flexibly, so that the power receiving portion 11 can be brought into the engaged state with the driving head 50 from the pre-engaged state more flexibly and conveniently.
Example 6
Next, embodiment 5 describing the process cartridge of the present invention is described. As shown in fig. 15, since the blocking member 60 is provided on the right side plate on which the driving head 50 in some of the existing image forming apparatuses is located, the blocking member 60 is rotatably provided on the right side plate 102, and a locking member (not shown) for locking the blocking member 60 against rotation is further provided on a top plate (not shown) adjacent to the right side plate 102, when the process cartridge is mounted along the right side plate, it is necessary to unlock the locking member provided on the right side plate 102 to restore the rotation of the blocking member 60 to continue the mounting, and the locking member is a protruding structure mounted in a recess in the top plate of the image forming apparatus. Since the process cartridge in this embodiment needs to be tilted when the image forming apparatus is taken out, an auxiliary removing member is provided on the process cartridge. As shown in fig. 16, in the present embodiment, an auxiliary dismounting member mounting portion 1a is provided on a casing of the process cartridge, a through hole 20a is provided on the auxiliary dismounting member 20, the through hole 20a is mounted on the auxiliary dismounting member mounting portion 1a and rotatable, and a third elastic member 21 is provided between the auxiliary dismounting member 20 and the casing 1, one end of which abuts in a first end abutment portion 1c on the casing, and the other end of which abuts in a second end abutment portion 20c of the auxiliary dismounting member 20. The housing is further provided with a stopper portion 1b for contacting with a stopper portion 20b of the auxiliary dismounting member 20 to restrict the position of the auxiliary dismounting member 20. When the process cartridge is initially mounted into the image forming apparatus, the auxiliary dismounting member 20 is restrained at an initial position by the cooperation of the third elastic member 21 and the stopper portion 1b on the casing, which allows the lock member pushing portion 20d provided on the auxiliary dismounting member 20 to slide into the projection structure provided in the recess in the top plate of the image forming apparatus to unlock the lock member in the image forming apparatus when the process cartridge is mounted into the image forming apparatus, so that the blocking member 60 is restored to the rotation function, and the process cartridge pushes the blocking member 60 to rotate to complete the mounting. When it is necessary to take out the process cartridge, the auxiliary removing member 20 can be rotated against the elastic force of the third elastic member 21 as in fig. 6, so that the auxiliary removing member 20 does not come out of contact with the locking member in the image forming apparatus even in the inclined state to smoothly take out the process cartridge. When the process cartridge is completely removed from the image forming apparatus, the auxiliary removing member 20 is again restrained at the initial position by the combined action of the elastic member 21 and the stopper portion 1b on the casing to facilitate the next installation.
Example 7
Next, embodiment 6 describing the process cartridge of the present invention is described. As shown in fig. 17 and 18, the present embodiment is different from embodiment 1 in that the force receiving portion in embodiment 1 is eliminated in the present embodiment, and the power receiving portion in the present embodiment is provided so as to be movable in a direction perpendicular to its own rotation axis. In this embodiment, the fourth elastic member 31 is provided on the bracket 30 supporting the power receiving portion 1101, one end of the fourth elastic member 31 abuts against the bracket 31, the other end abuts against the power receiving portion 1101, and a cover plate 32 covers the fourth elastic member 31 to prevent the fourth elastic member 31 from falling off. In order to achieve the movement of the power receiving portion 1101 in the direction perpendicular to its own axis, it is preferable to provide the power receiving portion as a power receiving portion 1101a, a power transmitting portion 1101c and an intermediate connecting portion 1101b. A claw portion 1101a2 and a first sliding protrusion 1101a1 are provided on the power receiving portion 1101a, a first guide chute 1101b1 and a second guide chute 1102b2 are provided on the intermediate connection portion 1101b, a second sliding protrusion 1101c and a shaft pin mounting hole 1101c1 are provided on the power transmitting portion 1101c, one shaft pin 1101d is mounted in the shaft pin mounting hole 1101c1, and the shaft pin 1101d can transmit the driving force of the power transmitting portion 1101c to the flange 15. Wherein the power transmission portion 1101c is mounted in the flange 15 and fixed with respect to the flange, the first sliding protrusion 1101a and the first sliding guide groove 1101b1 are engaged and relatively slidable, the second sliding guide protrusion 1101c2 and the second sliding guide groove 1101b2 are engaged and relatively slidable, and the extending directions of the first sliding guide groove 1101b1 and the second sliding guide groove 1102b2 intersect each other, preferably at 90 degrees to each other, such that the power reception portion 1101a is free to move with respect to the power transmission portion 1101c without directional restriction in a direction perpendicular to the rotation axis of the power reception portion 1101. In this embodiment, the fourth elastic member 31 is used to control the movement of the power receiving portion 1101a, when the process cartridge is mounted in the image forming apparatus, when the power receiving portion 1101a interferes with the driving head 50 (see fig. 4) in the image forming apparatus, the power receiving portion 1101a is pressed by the driving head 50 to move against the elastic force of the fourth elastic member 31, and when the machine door is closed and the driving head 50 is rotated by the driving head of the image forming apparatus, the fourth elastic member 31 pushes the power receiving portion 1101a in a direction approaching the driving head 50 to achieve engagement of the claw portion 1101a2 and the power output arm 50a of the driving head 50 as the driving head 50 rotates. In the present embodiment, the power receiving portion 1101 is preferably divided into 3 parts to achieve the effect that the power receiving portion moves in the direction perpendicular to the rotation axis of the power receiving portion, alternatively, the power receiving portion may be made into a single piece to move, and after the power receiving portion is integrally moved, only enough space for the power receiving portion to move needs to be reserved in the hollow portion of the flange.
In the above embodiment, the power receiving portion is provided immovably with respect to the rotatable member in the axial direction of the rotatable member, in other words, the claw portion of the power receiving portion has a first distance with respect to the rotatable member in the first state, the claw portion of the power receiving portion has a second distance with respect to the rotatable member in the second state, the above first distance is set equal to the second distance, and the stability of power transmission between the power receiving portion and the rotatable member can be greatly increased as compared with the prior art in which the power receiving portion is provided in a telescopic structure with respect to the rotatable member.
According to the processing box provided by the invention, when the power receiving part in the processing box is interfered with the driving head in the imaging equipment, the power receiving part is driven to rotate by the rotation of the driving head through the contact of the power receiving part and the driving head so as to overcome the interference state to achieve smooth installation, and meanwhile, the processing box is obliquely taken out to ensure smooth taking-out of the processing box. The technical problem that a power receiving part in a processing box in the prior art cannot be normally meshed with and disengaged from a driving head in imaging equipment is solved.
The foregoing embodiments are merely for illustrating the technical solution of the present invention, but not for limiting the same, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that modifications may be made to the technical solution described in the foregoing embodiments or equivalents may be substituted for parts of the technical features thereof, and that such modifications or substitutions do not depart from the spirit and scope of the technical solution of the embodiments of the present invention in essence.
